Question

Hi, I am working on MIT 6.189 in hw_2 Ex 2.3
my math functions work in the command line when I use math.sin(math.pi) for example, but when I put the sin and cos values in the multadd function python seems to not recognize the math.sin and math.cos. i tried calling the math library inside the multadd function but it did not work. Does anyone know how to fix this?

Answer 1

Is it tossing any errors?

Answer 2

Hi, yes this is the error

Traceback (most recent call last):
File "C:\Users\Sotero\Desktop\Python HW\hw2.py", line 76, in <module>
b=math.cos(math.pi/4)
NameError: name 'math' is not defined

Answer 3

What import statment(s) did you use?
```
from math import *
```
Is not that great. You might try:
```
import math
```
They did that poorly in the MIT class.

Answer 4

I did import math .Apparently, I have to be in the command line to write the formula. It does not work in the shell.It is working now. Thanks for your help :)

Answer 5

Strange. I wonder if it has some pathing issue.
